Abstract (en)

[origin: EP2784992A1] Node devices of a mesh communications network are interconnected by links. Forwarding tables are initially built following a link-state routing protocol. Each node device performs, upon detecting a link failure or a link recovery: determining, from a local forwarding table, one or more data paths impacted by the link failure or restored by the link recovery; and, transmitting toward one end-point of each determined data path at least one message representative of said link failure or said link recovery and including identifiers of said determined paths. Each end-point, when receiving said message(s) representative of said link failure or said link recovery, records an indication of whether each data path identified in the received message(s) can be activated or not. When the received message(s) is(are) representative of a link failure, each end-point performs: selecting an alternative data path for each data path identified in said received message(s); and transmitting, for each selected alternative data path, a path switch message toward the other end-point of said selected alternative data path, aiming at activating said alternative data path instead of the corresponding data path impacted by the link failure.
